Operation & Maintenance Manual

General Information

This section refers to the various components which require periodic maintenance and
replacement.
The Maintenance Schedule indicates the various components' descriptions and the intervals
when maintenance has to take place. Fluid capacities can be found in the General Data
Section of this manual. For any specification or specific requirement on service or preventative
maintenance for the engine, refer to the Engine Manual.
Compressed air can be dangerous if incorrectly handled. Review all maintenance precautions
listed below before attempting any maintenance work on the compressor.

Maintenance Precautions

Prior to attempting any maintenance work, ensure:
1. All pressure is vented from the system and that the compressor cannot be
started accidentally.
2. If the Automatic Blowdown Valve fails to operate, pressure must be gradually
relieved by operating the Manual Blowdown Valve.
3. The discharge pipe/manifold area is depressurized by opening the Discharge
Valve, while keeping clear of any airflow from it.
4. Maintenance personnel are adequately trained, competent, and have read the
Operation and Maintenance Manual.
Pressure will remain in the system between the Minimum Pressure Valve
and the Service Valve after shutdown and operation of the Automatic
Blowdown Valve. This pressure must be relieved by disconnecting any
downstream equipment and opening the Discharge Valve to atmosphere.
Prior to opening or removing panels or covers inside a compressor, ensure:
1. Anyone entering the compressor is aware of the reduced level of protection and
the additional hazards, including hot surfaces and intermittently moving parts.
2. The compressor cannot be started. Post warning signs and/or fit anti-start
devices.
3. Battery cables are disconnected.
